Once people outgrow fearing the consequences of stepping on cracks in the sidewalk, they tend to take the pavement beneath their feet for granted. Twelve years ago, Sealer Kings of Nashville's owner Bob was exactly the same way, until his recently sealed driveway cracked in no time at all. He did some personal research, performed the task himself, and so loved the results that he sold his gourmet food business and went into asphalt care.

Today, he still fights the good fight against cracks, and any other form of wear and tear experienced by driveways, parking lots, and sidewalks. As his secret weapon, he wields undiluted sealants that sink deep inside the asphalt. On top of that, he also mixes in latex or Diamond Shield Foritifier additives so that each coat he applies is as hard to wipe away as the memory of seeing your parents do the macarena.
